Twitter Suicide...

A young lady used twitter to announce that she had a gun and she's gonna kill herself because of what she was going through. No one tried to stop her because most folks on her twitter thought it was a joke.

My question is; are we so desensitized to killings to the point we ignore someone saying they're about to take their own life. At what point do we become concerned to the point we make a phone call to the cops letting them know that a online friend is spazzing out and you are concerned they may hurt themself? To the people on this young ladies twitter friend list I ask "SERIOUSLY, WTH WERE YOU THINKING"?
